SPECIFICATION forming part of Letters Patent No. 257,496, dated May 9, 1882.

Application filed January 3, 1882.

Toall whom it may concern:

Be it known that I, SAMUEL U. KING, of Cottage City, of the county of Dukes, of the State of Massachusetts, have invented a new and useful Improvement in Windmills; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a front elevation, Fig. 2 a side view, and Fig. 3 a vertical and longitudinal section, of a windmill containing my invention, the nature of which is defined in the claims hereinafter presented. Fig. at is a rear view of its main bevel-gear and the regulator applied thereto and to hub of the wind-wheel, such regulator being for the purpose of gov erning the slant of each of the wings of the wheel in order to maintain practical uniformity of the speed of the wheel as the velocity of the wind may vary from time to time.

In the said drawings, A denotes a tubular standard, having upon its upper part a frame, B, adapted to revolve on and around the said standard, and provided with a vane, O. The frame B has within and supported by it a horizontal shaft, D, provided with a double crank, E, upon whose wrist is a friction-roller, a, which extends into a slot, 1), of a rod, F, adapted to the frame B and the standard A, so as to move vertically therein, a section of the rod and crank being shown in Fig. 5.

Fixed 011 the shaft D, at its outer end, is a hub, G, provided with a series of radial arms, 0, each of which has applied to it, so as to be capable of revolving on it, a wing, H. A main bevel-gear, I, revoluble on the shaft D, is arranged in rear of the hub G, and engages with the wings by means of a series of bevel-pinions, K, fixed to the wings, there being one of such pinions to each of the wings. Two projections, d d, extending from the hub on opposite sides of the shaft and through spaces between the arms of the main gear, have arms L L pivoted to them at or near the inner ends of such arms. The arms are loaded at their outer ends with balls 6 c, and extend loosely through staples creyes ff, projecting front the main gear. As the speed of revolution of the windmill may increase, these arms will be so moved by centrifugal force as to turn the main gear on the shaft D, and cause it to simultaneously turn all the pinions K in a manner to reduce the slant of the wings to the direction of the wind, the reactive power of the springs M of the vanes affecting an increase of the (No model.)

ing back from it through guides or cars h fixed to the frame and vane. A cross-bar, i, extending from one to the other of the guide-rods g,

has a spring, 0, adapted to it and the vane,

such spring being to retract the annulus N. A line, 1), attached to the cross-bare and going down through the tubular standard A, serves to enable a person to advance the said annulus against a curved-finger, I, extending from one of the wings. By so advancing the annulus the said wings may be moved in a. manner to bring them edgewise to the wind in order to prevent it from revolving the wheel. While the wheel may be in revolution the rod F will be reciproeated vertically.

By means of the governor, as described, consisting of the weighted arms arranged with and applied to the hub and main gear, as set forth, the wind-wheel may be automatically regulated or maintained at a uniform speed, as the wind may either increase or decrease in velocity.

I am aware that before my invention there have been applied to a wind-wheel means of regulating the slant of its wings as the wind may vary in its velocity, and therefore I do not broadly claim such.

What I claim'as my invention is as follows:

1. The combination of the main and auxiliary gears I K, (applied to the wheel-shaft and wings as set forth,) the springs M, (ofthe wings and radial arms,) and the weighted arms L and their fulcra (1, adapted to the wheel-hub 5 and main gear, all being essentially as set. forth, and for governing the slant of the wings of the wind-wheel.

2. The combination of the annulus N and means for advancing and retracting it, as ex plained, with the rotary frame B, its supporting standard A, the curved finger P, projecting from one of the wings H, and with said wings and their supporting-arms c, and main and auxiliary gears I K, all being to operate substantially as specified.
